Apparently the operator lied. NH agreed to build him a hew gun but once examined they realized it was operator error as it was a squib that the shooter followed by another round.
Any 10MM gun would blow up under these conditions and IMO NH should not have eaten this mistake but they spoke too soon and will keep their word.

If I was Nighthawk I would tell that lying scumbag to eat s';t and die!
They are showing really good customer service by providing him with a new gun after he knowingly lied to them about the cause of the failure.
